To aZZ whom it may concern: I

Be it known that I, WILLIAM C. LOEFFEL, a citizen of the United States,residing at the city of St. Louis, State of Missouri, have invented acertain new and useful Improvement in Folding Packings, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, forming part ofthis specifica- Figure 1 is a detail view of my improved folding packingin position in a portion of a box. Fig. 2 is an enlarged verticalsectional view through said folding packing. Fig. 3 is a horizontalsectional view on line 3 3, Fig. 2. Fig. 4 is a detail view of one. ofthe wire clips used in connection with my improved folding packing. Fig.5 is a detail View of a modified form of clip. Fig. 6 is an elevationalView of the clip shown in Fig. 5. Fig. 7 is a modified form of clip,illustrating the same as being stamped or otherwise shaped from sheet.metal. Fig. 8 is a sectional view illustrating the manner of attachingthe clip shown in Fig. 7. Fig. 9 is a modified form of a sheet-metalclip. Fig. 10 is a top plan View of the same as applied to a strip of myimproved packing.

This invention relates to a new and useful improvement in foldingpacking especially adapted for use in boxes or other inclosures.

for spacing apart frangible articles.

The object of my present invention is to construct a cheap form of clipwhich is easily applied to strips forming the packing, said clipsaffording means of attachment between said strips, and also byreceivinga pivot rod or wire, acting as a hinge, enabling the packing tobe folded when not in use.

With this object in view the invention consists in the construction,arrangement, and combination of the several parts, all as willhereinafter be described and afterward pointed out in the claims.

In the drawings, A indicates a portion of a box, in which is shown asection of my improved packing in position. The packing con sists ofparallel strips arranged on different planes,which strips when in anoperative position intersect each other to form proper spaces verticaldisplacement and also act as hinges by which the strips may be foldedone upon the other.

B indicates a clip which, as shown in Figs. 1 to 6, consists of a wirebent into suitable shape to provide eyes at its extremities, which.project beyond the edges of the strips, the ends of said wires beingbent so as to be embedded in the strips and hold the clips againstdisplacement.

1) indicates the eyes above referred to, which are spaced apart asufficient distance to receive the strip between them, said eyesprojecting beyond the farther edge of the strip. The body portion of theclip rests against what I will term the back of the strip,

while the two ends I) of the wire pierce the strip and are clenched onthe face thereof.

:When the clips are in position, the bent securing ends andtheprojecting eyes prevent any undue movement of the clip on the strip.The strips being provided with these clips equidistant apart are thenarranged so that the eyes of one series of strips will register with theeyes of the clips on the next adjacent series, which last-mentionedseries of strips are arranged at an angle to those first placed. inposition.

The packing being built up with as many series of strips as desired, arod or wire 0 is threaded through the registering eyes until the endofsaid rod projects beyond the last eye of the series, when the same isbent over at c, as shown in Fig. l. The other end of this rodis likewisebent over, so that this pivot-wire in function acts as a binding mediumto hold the packing together, as well as serving the purpose of afulcrum on which the different strips are pivoted.

Fig. 2 shows the wire 0 being passed through the registering eyes ofclips on different series of strips.

In Figs. 7 and S I have shown the clip as being made of sheet metal, thebody portion D thereof beingstruck up at d, the struckup portions beingadapted to be embedded in end of the clip is bent at an angle to formears (1', which are perforated for the passage of the wire 0.

In all forms of clips heretofore described the body portion of the cliprests against what I have termed the back of the strip, while the eyesor ears through which the pivot Wire is to be passed project beyond thefront face thereof, so that when said pivot-wire is inserteditmaterially assists in holding the clip in position. It will be notedthat the pivot-wire in the above-described constructions rests againstthe face of the strip.

In Fig. 9 the modification shown is of a sheet-metal clip, the bodyportion E resting against the back of the strip, while the ends are bentover and inwardly on the front face, so that the ears e will be locatedwithin the lines ofthe strip. The material of the clip resting againstthe front facein this construction acts asa wear-surface for thepivot-rod and serves to protect the strip from abrasion thereby; also,by reducing the surface with which the rod contacts the friction iscorrespondingly reduced.

I am aware that minor changes in the arrangement, construction, andcombination of several parts of my device can be made and substitutedfor those herein shown and described without in the least departing fromthe nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is V 1. In a packing,the combination with strips,

of clips secured to said strips equidistantly, and pivot wires or rodspassing through said clips to bind the packing together; substantiallyas described.

2. In a packing,the combination with strips, of clips secured to oneside of said strips and extending over and beyond the opposite side ofsaid strips, and a binding rod or Wire which passes through theprojecting ends of said clip; substantially as described.

3. In a packing,the combination with strips,

of clips whose ends are bent over and project beyond one face of saidstrips, and a rod or wire which passes through registering open= ings inthe projecting ends of said clips; subwhereby said clip is held inposition; sub

stantially as described.

In testimony whereof I hereunto affix my signature, in the presence oftwo witnesses, this 18th day of May, 1899.
